If you are working on design of your website or software and looking for a quick way to sketch user interface mockups, head straight to MockFlow.com. It is a web tool that makes the process really easy and there is no installation.

The application has a clean interface and editing feature-set is minimalistic and well organized. Simply drag and drop ‘shapes and elements’ onto the whiteboard and then customize them by resizing and moving around. Is much faster than drawing designs manually, hence all possible custom components are already there.

There is also an option to collaborate on mockups with others.

Mockflow provides free and paid plans – A free plan lets you create as many mockups as you like and has limit of 4 pages per mockup, 10 MB storage, and 2 previewers.
